THILLMCOUPLING.

SPECIFICATION forming part of Letters Patent No. 306,347, dated October 7, 1884. Application led `Tune 12, 1884. (No model.)

To all whom t may concern:

Be it known that I, AARON B. PERINE, a citizen of the United States, residing at ToV peka, in the county of 'Shawnee and State ot' Kansas, have invented certainl new and useful Improvements in Thill-Gouplings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a plan view of my device with the thill detached. Fig. 2 is a vertical sectional view of the same, and Fig. 3 is a transverse'sectional View.

This invention has relation to spring-steel anti-rattlers for shaft-couplings, and it consists in the construction and novel arrangement of devices, as hereinafter set forth, and pointed out in the appended claims.

In the accompanying drawings, the letter A designates the shackle-clip, which is attached to the axle. This clip has the arms B, which are perforated at c for the passage of the headless pivot-pin d. A shoulder, c, is formed on the shackle where it joins the clipband g, and a shoulder, h, is usually formed in the lower back portion of the shackle.

C represents the eye ofthe thilliron D.

K represents the spring-steel anti-rattler, which is made, preferably, ofa single piece of bandsteel, bent in form as hereinafter set forth. First, the end ot' the steel band is bent to provide an offset, l, which engages the shoulder e of the shackle-clip, and therein the steel band, seated in the interval between the shackle-arms, descends below said arms in front of the offset l1., and returning in loop the shackle-ar1ns upward. i Then the branches of the band are brought to engage one another, as shown at c, to, form the portion of double thickness, which bears against the back of the eye C of the thill-iron, and operates to prevent the rattling thereof upon the pivot-pin. A rivet, b, passed through the doubling a below the bearing part, is designed to hold the branches together if the front part should happen to be worn through by the working of the eye of the thill-iron. The front or bearing branch, F, of the double por- .tion of the band descending below the arms of the shackle is bent upward in front, as shown at o, and being split in the middle from the point k, the lateral arms E thus formed are spread and twisted one-quarter around, as indicated at w, so that the terminal portion z will fit neatly against the outside surfaces of the arms B of the shackle, covering the apertures c, and holding the pivot-pin in position. The front loop branch, F, which is divided to forni the guards for the pivot-perforation, holds its position without being affected by the pressure upon the back portion which forms the anti-rattler. This steel-band antirattler is effective and durable, is easily manufactured, and readily applied. i

Having described this invention, what I claim and desire to secure by Letters Patent, 1s-

l. The spring-steelband anti-rattler,having l the rear spring loop doubled at c to form the spring bearing riveted at b, and having the looped front portion split and spread in twisted form-to provide the side guards for the pivotfpin, substantially as specified.

2. The combination, with the shackle-clip and thill-iron, of the spring-band doubled at c to form the bearing against the eye of. the thill-iron looped downward below the arms in rear of said bearing to engagev the shackle, and looped downward in front and split to form the guards at the sides of the shacklearms for the pivot-pin, substantially as specified.

In testimony whereof I afiiX my signature in presence of two witnesses.

AARN B1. PERINE.
